Patent DE-2101169-A1 (DE)
Title: Reactor interspace scanning - with mechanically operated probe
IPC: G21C17/00
Filed: 1971-01-12
Abstract: A mechanically operated probe for scanning the interspace between the reactor core and cover plate with particular application to reactors with rotary covers. Teh probe is housed within a vertical guide tube passing through the cover plate into the interspace. Within the guide tube are two vertical counterbalanced rods which at their upper ends are coupled to hydraulic or pneumatic drive units and a their lower ends to pivot and slotted arm linakges which constrain to hold the probe arm in a retracted or released state. In the released state the probe swings down to a horizontal position and rotation of the guide tube assembly produces a horizontal seam. Actuation of the drive units moves the rods and linkags to retract the probe into the guide tube. Demountable features have advantages for reactor operation and maintenance.

Patent DE-2320747-A1 (DE)
Title: Grating mfr. by continuous shear and bar insertion - slots sheared in rows with automatic insertion and pressing of crossbars
Inventor: TRUNT ERNST
IPC: B21D47/00
Filed: 1973-04-25
Abstract: A row of bars with a rectangular cross-section is clamped in a bed which can be moved underneath a press-head. The head contains a row of shearing tools and a punch and there is also a reciprocating magazine which hold the cross-bars, i.e. the bars which will be inserted at 90 degrees in the row of slots, and also on edge, to form a grating. The shearing tools operate through a matrix which contains a row of slots supporting the lower, rectangular bars; a second row of slots in the matrix act as channels for the shearing tools. Also a row of slots is sheared in the rectangular bars, a cross-bar is dropped in the slots and the punch drives the crossbar into position; some deformation is involved in the pressing operation so that a strong joint is obtd. Bars can be carried past the slotting shears so that a continuous cycle results: slot/insert cross-bar/press cross-bar.
Patent DE-2323294-A1 (DE)
Title: Safety nozzles for autogenous welding equipment - with spring-loaded return valve and flame barrier to stop blow-backs
Inventor: BORNMANN HANS
IPC: F23D14/46
Filed: 1973-05-09
Abstract: In normal operation, gas flows down one side of the nozzle into a central cylinder, which houses a spring-loaded valve; after going through the valve, the gas passes through a disc of porous sintered material, which also supports the spring, and then out of the nozzle. If there is a back-fire, causing a shock-wave, the flame is held back by the sintered disc which acts on the spring-loaded valve, keeping it closed, i.e. this is a back-flow barrier valve. The blow-back can then go through the sintered disc past a second spring-loaded valve into a chamber from which it can enter the top of the central cylinder; it then presses on a piston which seals the entry-port to the main valve, thus effectively preventing any after-flow.
Patent DE-2337025-A1 (DE)
Title: Ion etching process for miniature printed circuits - which prevents undercutting of conductors, uses photolacquering process
Inventor: RICKER THOMAS DR RER NAT
IPC: H05K3/08
Filed: 1973-07-20
Abstract: Etching by means of a high voltage discharge process is of use in the manufacture of miniature printed circuit boards where the distance between conductors is less than the conductor thickness, and also where the conducting layer is very thin. There are no chemical byproducts requiring rinsing away, and the undercutting of the conductor is eliminated. The process is typically carried out in an inert gas atmosphere at 10-2 Torr, at a d.c. potential of 3-6 kV. Argon is used as the inert gas. The photolacquer used in the process may be replaced by oxidised aluminium or chromium.

Title: Rotary piston machine - has flap valve preventing pressure medium through flow to outlet
Inventor: ZILLNER GUENTER
IPC: F01C1/46
Filed: 1973-11-27
Abstract: Rotary piston machine with one or several rotary pistons, eccentrically located on a shaft, which rotate tightly against covers in full circumference in a corresponding number of cylinder chambers, and at their furthest extent around teh centre line of the cylinder bore against the housing disc cylinder bore surface. Pressure medium, i.e. gas or fluid enters through an inlet port in the housing disc wall over a flap valve on the circumferential surface of the piston and presses the valve to the piston. The valve due to its swivelling ability, slides on the piston surface and prevents direct through flow of the pressure medium to the outlet aperture in all rotary positions of the piston. By virtue of its length, the valve has a less than 90 deg. swivel angle, and by reason of its swivel angle only permits one direction of rotation of the rotary piston.

Title: Air system to keep rear lights clean - is powered by engine cooling fan behind radiator and in front of channels
Inventor: DEUTENBACH KLAUS-RAINER
IPC: B62D35/00
Filed: 1974-05-10
Abstract: Two air channels are provided which run either side of the vehicle along the main beams which may themselves form the necessary air channels. At the rear of the vehicle is a beam, running at 90 deg. to the vehicle's longitudinal axis. The beam is located above the rear light cluster and directs the warm air flow down through an opening and across the surface of the lights. This stream of warm clean air forms a barrier between the light cluster on one side and the dead water region on the other side behind the vehicle. The rear light cluster is kept clean, ensuring that when in operation the lights can be readily seen by following vehicles.

Title: Compression ignition engine for motor vehicle propulsion - has compression and working pistons with common crankshaft
Inventor: KIENER KARL DIPL ING
IPC: F02B33/22
Filed: 1974-05-15
Abstract: Engine is an improvement to 410948, whereby air is induced and then compressed by one piston before being transferred to a working piston where fuel is injected and ignited by the heat generated by the compressed air. The working piston and the compressor piston reciprocate together from a common crankshaft and the respective cylinder heads each contain inlet and exhaust valves running counter to each other so that the pressure valve (6) opens during the compression stroke enabling air to pass into an air storage chamber (102) arranged in the cylinder head and connecting the two cylinders. The transfer valve (114) in the working cylinder head remains open practically for the entire expansion stroke. The working piston crown has a blunt conical projection (110) which fits into a corresponding recess in the cylinder head to form an ante chamber (40).
